Patented Oct. 12, 1937 UNITED STATES LOCOMOTIVE TENDER William C'. Meyer, Altoona, Pa., assignor to The Pennsylvania Railroad Company, Philadelphia, Pa., a corporation of Pennsylvania Application July 17, 1936, Serial No. 91,154 6 claims. (o1. 10754-231)q This invention relates to streamlined locomotive tenders, and more particularly to the superstructure of such tenders and the manner in which storage tank openings are rendered accessible through the exterior streamlined casing.

AS set forth in the co-pending application of Raymond G. F. Loewy and Harold A. Nonemaker, Serial No. 91,152, filed July 17, 1936, there are a number of advantages to be derived from the scientific streamlining oflocomotives. These yadvantages are best realized when the tender used in conjunction with the locomotive is also streamlined in conformity with the contour of the locomotive, the exposed surfaces of the boiler, cab and tender being substantially continuous and so formed as to create va minimum of disturbance of the atmosphere through which the tr-ain travels. In the streamlining of the locomotive tender, it is desirable to extend the side walls proper upwardly to the level of the cab roof and to shape such extensions in conformity with the cross sectional outline of the cab.

However, the provision of a streamlined casing extending upwardly from the side walls proper of the tender introduces a difliculty with respect to the accessibility of the filling openings of the storage tank. The water tanks of tenders are customarily iilled by means of a spout which swings over the top of the tender to a position above the inlet to the storage tank to be iilled. Due to a number of considerations, such as the presence of overhead wires in electrified territory, andthe structural details of the water columns and spouts in general use, it is not desirable to extend the height of the spout, Iand it is unsafe to have an attendant stand at a level near the `electric wires when filling the tanks.`

Therefore, the main object of this invention is to overcome the above recited difficulties by the provision in a tender of a streamlined casing conforming to the cross sectional outline of the locomotive and having -a readily movable section Awhich permits the storage tanks to be iilled at the customary level and without change in the construction of the wayside water spouts now in use.

`Other objects and advantages of the invention will appear in the detailed description of a preferred embodiment thereof which follows, and which has reference to the accompanying drawings, whereof:

Fig. I shows a side elevation of a locomotive tender embodying the invention.

" Fig. II shows a vplan view of the locomotive tender shown in Fig. I.

Fig, III shows an enlarged plan View, partially broken out, of a portion of the tender in the region surrounding a storage tank opening.

Fig. IV shows Ian enlarged cross sectional View, taken as indicated by the arrows IV-IV of Fig. II.

Fig.` V shows an enlarged cross sectional view, 5 taken as indicated by the arrows V--Vof'Fig I.

Fig. VI represents a fragmentary sectional view on an enlarged scale, taken as indicated by the arrows VI-VI of Fig. V, and showing details of one of the tracks and rollers employed for guidingv 10 a movable section of the streamlined casing.

In the drawings, there is shown a locomotive tender which is of conventional form with regard to the running gear, underframe, and coal and water storage compartments, but which has a superstructure `added thereto embodying the improvements of the present invention. The tender is provided with flanges I extending upwardly and inwardly in continuation of theside walls proper 2 of the tender and forming a partial 20 streamlined covering. The curvature of the flanges I desirably conforms with the cross sectional outline of the streamlined locomotive with which the tender is associated, and preferably the flanges I are joined together at the forward end of the tender by a bridge portion 3, thus dening a U-shaped exterior casing with a longitudinal passageway formed between the two sides. YLocated within the tender is the usual storage tank '4, having filling openings 5 at each side normally 30 closed by hinged covers 6.

Each of the extension flanges I forming the exterior casing for the superstructure of the tender has a movable section I adjacent to one of the filling openings 5. Such movable sections 1 have pairs of rollers Il thereon guided for movement horizontally and transversely across the top of the tender by engagement with parallel tracks 9, which are curved downwardly at their eX- tremities, as clearly shown in Fig. V, thus insuring 40 a secure seating of the movable section "I when it is in its normal position iiush with the outer surface of the flange I. The tracks 9, as clearly shown in Fig. VI, are in the form of channels and are supported by suitably spaced brackets III. The rollers 9 are free to rotate about the stub shafts I I which are attached tothe framework of the movable section I, and are secured in place by nuts I3 and washers I Il. Eachmovablesection 'I is provided with a number of stops I5, preferably in the form of angles, which seat against shoulders i2 at the top edges of the side walls proper 2 when the movable section is in its normal positionV substantially flush with the exterior surface of the flange I. At its upper end, each movable section 1 is 55 provided with locking means in the form of latch bolts Iii movable by handles II engaging keepers I8 attached to the lianges I at each side of the movable section.

Each movable section 'I preferably comprises a framework built up of angle bars secured together by gusset plates I9 at the corners, the movable section 'I in its cross sectional outline being in the general form of a quadrant of a circle.

When it is desired to gain access to a filling opening 5 for the purpose of cleaning or lling the storage tank 4, the corresponding movable section 'I is unlocked by disengaging the latch bolts IIS and is moved inwardly along the parallel tracks Il to a position within the longitudinal passage- Way at the top of the tender just beyond the position shown in dot-and-dash lines in Fig. V. The cover 5 of the filling opening 5 to be used is then swung rearwardly to the position indicated in dot-and-dash lines in Fig. V. When the movable section 'l has thus been moved inwardly beyond the filling opening 5, the tank I is readily accessible and may be filled in the customary manner by the ordinary wayside water spout. The movable section I is returned to its normal position after closure of the cover B of the lling opening 5, by pushing the same along the tracks 9 outwardly until the stops I5 are seated against the shoulders I2 at the side walls proper 2 of the tender. This seating of the movable section I is carried out by the gravitational thrust imparted by the downward curve of the tracks 9 at their extremities. 'Ihe latch bolts I6 are then operated to lock the movable section, and when locked the exterior surface of the section I merges with the adjacent surfaces of the ange I to form a smooth continuous exterior casing.

It will be apparent that a tender constructed according to the present invention gains the desired advantages with respect to streamlined contour, and at the same time renders the water tanks accessible in the customary manner. Therefore, no changes in the construction of existing water spouts are required, and no additional hazards for the fireman or other filling attendant are created.

While one particular embodiment of the invention has been described in detail, it is to be understood that various modifications or changes may be had with respect to the contour of the streamlined casing, the form of the movable section, and the manner in which it is operated, all without departing from the spirit of the invention as defined in the annexed claims.
